PaO2: ______________
PCO2: _____________
,pH:___________
Vital Capacity: ___________
Neg. Inspiratory Force:____________
FEV1:___________________
-Apnea or bradypnea
-Respiratory distress with confusion

-Confusion with need to protect airway
-Circulatory shock
Negative pressure ventilator - Type of Ventilator:
-Noninvasive
- (-) pressure forces air in
-Used for neuromuscular disorders
-Example: Iron lung, Chest cuirass
Positive pressure ventilator - Type of Ventilator:
-Invasive-- needs endotracheal tube
-Inflates lungs by exerting (+) pressure
-Pushes air in and forces aveoli to expand during inspiration
-Expiration occurs passively
-Example: Pressure cycled, volume cycled, high-frequency oscillary support
Pressure cycled
volume cycled
high frequency oscillary support - Positive Pressure Ventilators:
Pushes air in until pressure is met?
Pushes air in until volume is met?
Pushes air in at high rates and a low volume?
